What kinds of space and matter can light travel through?

Answers

Answer 1

Answer:

Answer:

Every material and the void.

Explanation:

Light is a kind of electromagnetic wave and electromagnetic waves do not need a medium to propagate itself. Light can travel through every medium and even in void.

Three balls leave the edge of a table at the same time. Ball A rolls off the table with an initial horizontal velocity. Ball B is launched at an angle and has both an initial horizontal and vertical velocity. Ball C is dropped from rest, and has no initial velocity.a) Explain which one(s) hit the ground first.

b) Explain which one(s) hit the ground last

Answers

Explanation:

Balls A and C have the same initial vertical velocity of zero. Therefore, they land at the same time.

Ball B has a positive initial vertical velocity, so it hits the ground last.

A weightless spring is stretched 10 cm by a suspended 1-kg block. If two such springs are used to suspend the block, one spring above the other, to effectively provide one double-length spring, then the total stretch of the double-length spring will be

Answers

Answer:

total stretch of the double-length spring will be 20 cm

Explanation:

given data

length x1 = 10 cm

mass = 1 kg

mass = double = 2 kg

to find out

the total stretch of the double-length spring will be

solution

we can say here spring constant is

k = mg ............1

k is spring constant and m is mass and g is acceleration due to gravity

so for in 1st case and 2nd case with 1 kg mass and 2 kg mass

kx1 = mg .........................2

and

kx2 = 2mg ........................3

x is length

so from equation 2 and 3

$(kx1)/(kx2)= (1mg)/(2mg)$

$(x1)/(x2) = (1)/(2)$

$(10)/(x2) = (1)/(2)$

x2 = 20

so total stretch of the double-length spring will be 20 cm

Resonance is the answer. Resonance frequency is the term used when an object begins to vibrate at an perferred frequency.

In a compressional wave the denser the medium is at the compressions the smaller is amplitude?

Answers

Wellll, let me think about that ...

I don't think I'd agree that you can characterize the amplitude of
a wave according to the density at only one point in it. After all ...
a tiny wave in steel would be much denser at a compression than
a huge wave in air would be.

The amplitude of any wave is described as the difference between
a peak and the resting value. Or even better ... half of the difference
between a maximum and a minimum.

So if you're looking at a longitudinal wave, like sound, I'd say if you
want to describe its amplitude, then you have to look at the density
at two points ... either the difference between the compression and
the resting densities, or the difference between the greatest compression
and the greatest rarefaction.

That's my opinion. I could be wrong.
